The function f(x)=-(x-3)^2 +9 can be used to represent the area of a rectangle with the perimeter of 12 units, as a function of

Ivenika [448]

Maximum area of the rectangle is $9cm^{2}$

Explanation:

Considering the dimensions to be in cm

$f(x) = -(x-3)^{2} +9\\f(x) = -(x^{2} +9 - 6x)+9\\f(x) = -x^{2} +6x\\f'(x) = -2x+6\\-2x+6 = 0\\2x=6\\x=3cm\\\\$

Putting the value of x = 3

$Perimeter = 2(x+b)\\12 = 2(3+b)\\6 = 3+b\\b= 3cm$

$Area of rectangle = x X b\\ = 3 X 3\\ = 9cm^{2}$

Therefore, maximum area of the rectangle is $9cm^{2}$

Storing milk at temperatures colder than 35°F can affect its quality of taste. However, storing milk at temperatures warmer than

puteri [66]

t > 35 and t <40

So, Option A is correct.

Step-by-step explanation:

This is the question of compound inequality

Since the temperature of milk should be greater than 35 and the temperature should be less than 40 for keeping the quality of milk.

So, Representing it in inequality the union of both conditions we get:

t > 35 and t <40

So, Option A is correct.
